Abstract: 324,112. Jensen, C. A., (Jenkins Petroleum Process Co.). Oct. 18, 1928. Hydrocarbons, cracking. - In a process for cracking oils of the kind in which oil is forced continuously under pressure through a closed cyclic channel part of which is heated to cracking temperature, fresh oil being continuously supplied while the vaporous products and the liquid residues are continuously withdrawn, clogging of the channel by carbon deposits is prevented by forcing fresh oil into that part of the channel from which the residual oil is withdrawn. The closed cyclic system may comprise a still 7 and a bank of cracking tubes 15 connected by front and rear sluiceways 13, 13<1> and drums 14, 14<1>, the oil being circulated by a propeller 20. The vapours pass off to a dephlegmator 6 where the heavier constituents are condensed by the crude oil introduced through a pipe 2 the condensate and crude oil being returned to the still through a pipe 12. About 45-65 per cent of the unvolatilized heavier constituents are rejected at short intervals from the drum 14, Fig. 2, through perforated nipples 22<1> and pipes 23, 28 while during the intervals of non-rejection fresh oil is pumped in through a pipe 29, the pipe 23 and the nipples 22<1>, the valves 31, 26, 24 being suitably manipulated.

Title: Communication and signal translation systems
IPC: H04B1/64
Filed: 1947-11-17
Abstract: 657,546. Automatic volume control; gramophone pick-ups. MULLER, E. N. Nov. 17, 1947, No. 30285. [Class 40 (iv)] [Also in Groups XXXVIII and XL (c)] A signal translation system comprises means for automatically producing or deriving auxiliary signals denoting discrete values of signal level and applying them for selecting or adjusting in stepwise manner corresponding amplitudes of main signals at a transmitter or recorder, or at a reproducer restoring the original amplitudes, the " main " and " level " signals being concurrently impressed on or derived from a single transmission or recording medium to provide accurate relative timing. The system is described applied to a multiplex pulse communication system in which succeeding pulses of one auxiliary channel periodically indicate in turn the compression of the communication pulse trains, [see Group XL (c)], and to recording and reproducing. A pick-up (Fig. 13) comprises a flat condenser electrode SC supporting the stylus S, the spacing of which from a fixed electrode CS is stepwise varied by the depth of a disc or tape record groove, the latter being selectively and stepwise varied in depth during recording in accordance with the volume level. The condenser capacity variation alters the frequency of an associated oscillator VA which is amplified, 'detected and passed through a high-pass filter CC producing at its output a sawtooth pulse 1p1 or 1p2 (Fig. 14) on each change of gain level. The positive or negative sawtooth pulses operate a trigger valve pair MV with alternative stable states to restore the correct gain level. Alternatively the recording stylus may be restored to normal record groove depth after recording a level change pulse of type 1p1 or 1p2. Further, a series of pulses 1p3, 1p4 ... may be recorded during one change of level which during reproduction may successively operate a control trigger circuit to minimise erroneous response due to a defective groove spot. The member SC may alternatively co-operate with an auxiliary magnetic structure or a piezo - electric cartridge.

Title: Directive antenna arrangements, particularly for use in radio direction finders
IPC: H01Q3/28
Filed: 1946-10-11
Abstract: 638,143. Radio aerials and direction-finding. STANDARD TELEPHONES & CABLES, Ltd. Oct. 11, 1946, No. 30401. Convention date, June 27, 1945. [Class 40 (vii)] A directive radio antenna arrangement comprises a single-turn, closed loop, conductor, a goniometer located at the geometric centre of the loop and a plurality of linear conductors separately connecting said goniometer to respective symmetrically spaced points on said loop. Preferably the linear conductors are connected to equally spaced points. A circular horizontal closed loop aerial 1 of diameter preferably less than a quarter wavelength at the mean frequency of the operating band is connected at equally spaced points by horizontal conductors 2-5 to a goniometer 11 mounted at the centre of the system. This goniometer may be of any type, but is described as similar to that of Specification 625,287. The output of the rotor of the goniometer may be connected to a direction-finding receiver feeding a signal amplitude indicator. Movement of the rotor rotates the figure of eight pattern of the system for direction finding. If left unscreened conductors 2 and 4, 3 and 5, may act as dipoles if the wavelength is short enough, the pattern of the dipole being the same as that of the loop so that the directional properties of the system are not affected. At longer wavelengths it is preferred to screen the conductors by tubular shields 32 connected to the casing 33 shielding the goniometer and having circular end plates 34 attached to their outer ends. The number and spacing of the conductors may be varied, e.g. there may be three equally spaced conductors, Fig. 4 (not shown). Likewise, rectangular or square loops may be employed. Fig. 5 shows a square loop 38 formed by the inner conductors of four coaxial lines, the outer sheaths of which are spaced apart at the corners of the square. Further coaxial lines 44-47 are connected to the mid-points of the sides and their inner conductors are attached to the loop at one end and to a goniometer at their other ends. This embodiment is stated to discriminate sharply against downwardly directed waves such as those reflected from the ionosphere.
